1. GENERAL & SAFETY INFORMATION
This section contains important safety and operation instructions. Please read and
retain this manual for future reference.
The DC-DC charger should be installed by a qualified Auto Electrician with
knowledge of automotive electrical systems. The following recommendations are to
be conducted prior to installation:
• The unit MUST not be disassembled for Safety and Warranty reasons.
• The DC-DC charger is designed for internal installation ONLY.
• Recommended cable size for input and output connections to unit need to be
followed. Output charging current of the DC-DC charger will depend on wire size of
the auxiliary circuits in the Charging Vehicle.
• Check and verify the input voltage is within the specifications of the unit. (Refer to
Specification table).
• Check and confirm the circuit connections to the Alternator or Vehicle battery and
Input to the INTELLI-GRID / INTELLI-RV (if connected) and the polarity is correct.
• Use the shortest possible cable lengths to connect the Input and Output circuits to
the unit.
• Ensure there is sufficient ventilation around the heatsink of the unit.
2. INTRODUCTION
2.1 GENERAL INTRODUCTION
PMDCS DC-DC chargers are designed to integrate with INTELLI-RV or INTELLI-GRID
battery/power management systems, but they can also function as standalone dual
battery chargers. They come with stripped and tinned, labelled input and output
wiring for ease of installation.
FEATURES
• Adaptive charge – adapts to smaller cables or excessive runs by adjusting the charge
rate to avoid overloading wiring.
• Non-isolation design with maximum efficiency of 96%.
• Euro-6 engine (smart alternator) compatible.
• Built-in multi-stage charging algorithm.
• Built-in automatic temperature and voltage compensated charging.
• Built-in fuse protection.
• Built-in heat sink for cooling.
• RS485 communication port for future options and upgrades.
• Protection against input/output over voltage, output over current, output short
circuit, internal over temperature, battery over temperature.
• Adjust current outputs and select battery type via dip switches.

The charging efficiency of the PMDCS is up to 96%.
PMDCS units also support communication of RS485.
Alternator type Alternator input voltage Working state
Conventional alternator 13.2V with 10 second delay on ON
12.8V with 60 second delay off OFF
D+ wired 11.7V ON
11.7V OFF
Note: If D+ is used and you want to switch to conventional alternator mode, disconnect
D+ and disconnect the PMDCS from the house/auxiliary battery and reconnect. This will
reset the system.
2.3 MULTI STAGE CHARGING ALGORITHM
The charging algorithm is microprocessor-controlled with a variable absorption charging
timer to ensure optimal charging for batteries with varying degrees of discharge.
Figure 2-2: Charging Algorithm
PMDCS will treat it as conventional engine rather
than Euro 6 engine.

2.4 BATTERY TEMPERATURE COMPENSATION
Correct charging of the battery is affected by its temperature, so the charging
formula must be adjusted automatically and in real-time based on the actual
battery temperature to ensure that the battery is fully charged but not overcharged
or undercharged. All charging voltages recommended by battery manufacture are
applied at 20°C – 25°C.
The BTS (Battery Temperature Sensor), terminated to the PMDCS, measures the
temperature of the battery and automatically makes adjustments at real-time to
properly charge the batteries at the default compensation rate of -3mV/°C/cell.
If the BTS is not present or connected, the PMDCS will use 25°C as the default
temperature setting.

2.5 DE-RATE CURVE AGAINST TEMPERATURE INCREASE
The PMDCS charger will monitor internal temperature to decide output power.
It will de-rate its output power against temperature increasing. The following
curve shows how the output power changes with an increase in temperature.
